The board utilizes an Altera MAX II CPLD for the following purposes:
■
Power-up configuration of the FPGA from flash memory
■
Embedded USB-Blaster
FPGA
■
Power consumption monitoring and display
Additionally, the MAX II device is also used to help dual-footprint the
FTDI and Cypress USB devices. Each has a shared path between the USB
device and the MAX II CPLD. The individual paths then drive to the
FPGA separately. Figure 2–3
